Ambassador Bridge, Michigan

The Ambassador is one of only three bridges connecting Michigan and Canada over its entire 721 mile water boundary. It connects the two largest cities on the Michigan/Ontario boundary, Detroit and Windsor. The bridge is the busiest commercial crossing on the entire boundary, with 8,000 trucks per day, nearly 3 million per year, carrying around half of the merchandise trade between the two largest trading partners in the world, Canada and the USA. The bridge is privately owned by a local billionaire named Manuel Moroun, who also owns the Michigan Central Railway building, an icon of Detroit decrepitude, and has investments in large trucking companies.  He is fighting plans to build a new bridge across the river, south of the Ambassador Bridge, though it has been approved by both the US and Canadian authorities and construction has started on the approach roads through Windsor.
